Hello, ever-inquisitive Python explorers! Are you up for a new adventure? Today, we’re diving into the world of online programming with Flask, a lightweight, user-friendly Python web framework. Consider **Flask **to be a toolset for developing web apps. It’s not just light and agile, but also surprisingly strong, offering everything you need to build a solid online application, from URL routing and template rendering to error handling. Furthermore, Flask allows you to start small and expand up, adding components and complexity as needed. Here’s an example of how to create a simple Flask application.:
from flask import Flask
app = Flask(__name__)
@app. route('/')
def hello_world():
return 'Hello, Flask!'
if __name__ == '__main__':
app. run(debug=True)
In this code, we’ve set up a basic Flask application that responds to requests at the root URL ('/') with a cheerful greeting: ‘Hello, Flask!’#### ExerciseNow it’s your turn to dip your toes into the refreshing waters of Flask web development:- Import the Flask module.
- Create a Flask web server from the Flask module.
- Create a route decorator to tell Flask what URL should trigger the function.
- Define a simple hello_world function that returns ‘Hello, Flask!’
- Tell your Flask app to run when the script is directly run.
Conclusion
Congratulations, eager coders! You’ve entered the bustling cityscape of Python web programming by establishing a small Flask app. Flask’s ease of use and adaptability make it an excellent choice for projects of all sizes. Remember that doing is the greatest way to learn, so keep exploring, iterating, and creating using Flask!
